A 12” long hitch with old 2” ball.  Also includes original older 1-7/8” ball and red cover. It mounts on the bumper and under car. This was on my 1965 camino since about new. About 25 years ago, I needed to tow with my 1964 Chevelle. I removed this unit from the El camino and mounted it on that car for a summer. I drilled the 4 same holes. Fit and worked perfectly, towed a few boats with that car. I replaced the bumpers on the El camino and don’t see me towing with it any more. Real easy to install, but you have to drill 2 holes in the bumper cross piece and 2 underneath on the frame cross bar. It should fit fine on any 60s GM A Body. I’m including my old chrome cross piece so you can measure from it and understand in the photos how simple it is. See the pics. It’s a hard to find, correct piece that can be rechromed, etc. Look close at the cool bolt head markings. It is missing a bumper bolt on one side, easy to get. Oldsmobile Buick GTO. It may fit other cars, with the other universal holes. Sold as is.
